Nest doesn’t shut humidifier off

I’ve connected an April site humidifier to my nest thermostat. It’s connected to a relay and the wiring seems correct. Initially it seemed to be working fine but now the thermostat is not shutting off the humidifier. Therefore it runs constantly when the fan is on. I’ve even turned the Hindi diet setting off but the water valve and fan continue to run. 

Is this normal?

Hello Eddy24san,

I'm sorry for the trouble this may have caused you — let's see what's going on.

To isolate, are you the one who installed your Nest Thermostat with your humidifier? In most cases, we strongly recommend professional installation for these systems because incorrect setup, either due to miswiring or wrong software settings, can cause weird Heating, Ventilation, and Air Conditioning (HVAC) behavior and even damage the HVAC system. I'd suggest contacting a local pro to examine your system to ensure its compatibility.

Please let us know if you have more questions.

Best regards,
